Hi,
You are probably all facing this: when you register with the API and login, your "username" gets prefixed with whatever login system you're using. The thing is, displaying the "simple<username>" instead of <username> across the game is a bit ugly. On the other side, using solely "<username>", there could be distinct players named identically, leading to all sorts of problems.
What's your take on this? What is the "best practice" here?
